In enzymology a tRNA-pseudouridine synthase I (EC 5.4.99.12) is an enzyme that catalyzes the chemical reactiontRNA uridine tRNA pseudouridineHence this enzyme has one substrate tRNA uridine and one product tRNA pseudouridine.This enzyme belongs to the family of isomerases specifically those intramolecular transferases transferring other groups. The systematic name of this enzyme class is tRNA-uridine uracilmutase.
